Arc Flash Protection – In a Flash (May 23, 2019)

Learn about new technology to reduce incident energy, protect personnel and equipment, and reduce downtime.

How Arc Quenching Switchgear works:
Arc Quenching Switchgear detects and contains an arc fault in less than 4 milliseconds, drastically reducing the incident energy. It works by detecting the ignition of an arc inside the switchgear using the Eaton Arc Flash Relay and transferring it to the Arc Quenching Device. Arc Quenching Switchgear transfers the arc by creating a lower-impedance arcing fault, not a bolted fault, safely contained inside the Arc Quenching Device. This reduces the peak fault current by at least 25% and puts less stress on upstream equipment during a quenching operation.
